PATENT EUBEN R. Borne, OF EPHRATAH, PENNSYLVANIA.

IMPROVEMENT IN WATER-WHEELS.

Specification forming part of Letters Patent No. 115,362, dated May 30, 1871.

I, REUBEN .R. ROYER," of Ephratah, in the county of Lancasterand State of Bennsylvania, have invented certain Improvements in the Buckets and LArrangementof Water- Wheels, of which the following is a specification: I

The nature of my invention consists in the curve of the buckets and their relation to the frustum of a conic side and dished top of the wheel so as to utilize the whole volume and pressure of the water in a downward and central direction, thereby gaining the maximum powerwit-h a freedischarge and reduced friction in a single series of. buckets.

The accompanying drawing will show th construction and manner of attachment, in

Figure 1 is a perspective view of the wheel and buckets combined; Fig. 2, the under side of thewheel,reduced in size; Fig. 3, the same seen from the top; Fig. 4, a section still more reducedin size; Fig. 5, a detached bucket, to

show itssev'eral parts forattachment.

A brief explanation will enable those skill ed in the art to make and use my invention.

The general plan is that of other waterwheels of this class, differing, however, in the curve'of the buckets and the plan and arrangement of the conic central dished top, and the adaptation. of saidbuckets to the conic sides in a single series, as shown. v

The flange F is slightly beveled inward.

The conicbasin or: central dish dips down about two-thirdsof the height of the wheel combined. Theordinary ring R supports the buckets below. The buckets B, Fig. 5, have an ear, E, perforated for a bolt, f, through the flange of the top F, towhich they are fastened, as also to theinclined or conic side O-of the top, by a flange, F,showin g two-bolt-holes, secured by nuts, shown in Figs. 1 and 3. The

endc of the bucket restson the base or frusturn of the cone. comesdown to a level with the bottom of the ringRa The outer edge of the bucket has a shoulder, r, resting onthetop of the ring,-

with a lug beneath it, It, for a screw-bolt orrivet to fastenit to the side of the ring R.

The doubly-curved face of the buckets, somewhat in principle to a mold-board on plows,

has the exterior surface concave, gradually The point 11 of the bucket velocity of motion to propel the wheel. H is a central hub, which supports the shaft 8. This shaft has its ordinary step and bearings, and the whole wheel is placed in any approved case and penstock, which are no part of my invention.

I am aware that patent No. 38,775, J une 2,"

1863, is constructed with the same object in view, in which the shaft hasits step in a post inclosed in a conical chamber. The bucket, although attached to the hub, (which is also the shape of an inverted frustum,) differs substantially in the construction and arrange ment of the buckets.

Patent No. 97,778. December 14,1869, also shows a conic-dished top so as to form two series of buckets with a vertical inletboth of which arrangements I disclaim. Nor do I claim a conic hub, in itself considered.

The peculiarly-curved face of my buckets, with the ear E, bevel or inclined flange F, shoulder r, and lug R, discharge-point d, in combination with the plain flange F of the conic basin 0 with itscentral hub H for the shaft, is an arrangement of parts which, by their combined and relative construction, is found, as practically tested, to be of superior efficacy and a decided improvement; therefore,

What I claim as my invention, and desire to secure by Letters Patent, is-

A bucket, B, with a doubly-curved face, and provided with a bevel flange, F, projecting ear E, shoulder 1", lug B, when said bucket is attached by a nut and bolt, f, through the ear E and flange F of the top, and the flange F of the buckets bolted through the conic sides 0 of the dished top, with its central hub H for the shaft 8, all combined in relation to each other in the manner shown, and for the purpose specified.
